What Quantum Strings can tell us about Quantum Gravity

TL;DR

This paper discusses recent advances in understanding nonperturbative bosonic strings, highlighting how certain theorems can be bypassed due to the theory's diffeomorphism invariance, shedding light on quantum gravity.

Contribution

It introduces new methods to overcome longstanding no-go theorems in nonperturbative bosonic string theory by leveraging diffeomorphism invariance.

Findings

Lattice and KPZ-DDK no-go theorems can be bypassed

Diffeomorphism invariance plays a key role in resolving nonperturbative issues

Progress enhances understanding of quantum gravity models

Abstract

I describe the recent progress in resolving two problems of nonperturbative bosonic string inherited from 1980's. Both the lattice and KPZ-DDK no-go theorems can be bypassed thanks to specific features of the theory with diffeomorphism invariance.
